* Added BTCParalelo price index for Venezuelan Bolivar VEF 

* Fixed all of the update_* functions on the exchange_rate.py plugin to indicate when there are SSL errors, there was a horrorous try-except-pass block that was drowning all the exceptions
* Added get_json_insecure to allow exchange rates over HTTP
